[osg-users] QOpenGLWidget in osgQt

I'm currently working on an app based on OSG 3.4.0 and Qt 5.6, targeting Win7 -- Win10.

Everythings was fine and smooth with Qt 5.5. I'm using osgQt::GLWidget, which is based on QGLWidget.

Since Qt 5.6, I've some hard unsolvable issues with QGLwidget. They are not related to OSG, and I can reproduce them with a Qt only example, but I also know that these problems are solved with QOpenGLWidget.

First, I would like to know if there is any plan for OSG to use QOpenGLWidget. 

If not, how hard would it be to make osgQt::QGLWidget inherit from QOpenGLWidget ? does anyone else tried it ? 

It was discussed in this topic : http://forum.openscenegraph.org/viewtopic.php?t=15097&highlight=qopenglwidget but it's about OSG 3.2.1 so I don't know how I can use it.

Thank you!
